When Perry goes in to have his first talk with Carla Cheney, she is “under restraint” for causing a disturbance in the jail the night before. We see her in a bed, wrists tied to the bed frame and her arms tightly covered by a restraining sheet. Carla spits venom throughout the interview and toward the end they cut to her and her arms are on top of the restraining sheet (wrists still tied). In the final cut of the scene, Carla’s arms are once again safely tucked beneath the restraining sheet. Submitted by Elsie of the Perry_Mason Yahoo Group, 5/13/2008.

Bernard Fox makes his only Perry appearance here playing Peter Stange. Bernard Fox was the only actor to appear in both the first Titanic movie, A Night To Remember (1958) and the 1997 version of Titanic. He also played the character of Dr. Bombay in three different television shows: Bewitched, Tabitha, and the soap opera Passions. But I will forever remember him for his character of Malcolm Merryweather on The Andy Griffith Show. Submitted by PaulDrake 33, 18 August 2009. +The Welsh-born actor appeared in 2 Columbos: as Purser Watkins in "Troubled Waters" & Detective Chief Superintendent Durk of Scotland Yard in "Dagger of the Mind" [IMDb].

Ravishing beauty Allison Hayes makes her fifth and final appearance on Perry Mason as "Cho Sin" a decidedly non-Asian playing an Asian role. What's more interesting is that there was no attempt outside of her wardrobe to make her Asian nor did she attempt any accent. In fact, I was completely unaware that her character was supposed to be Asian until I heard her character called "Cho Sin". Submitted by Kenmore 9/20/12

This is like a reunion episode of prior Perry Mason actors. There was the always classy Constance Towers, Jean Hale, John Abbott, and John Dall. Submitted by Perry Baby 12/28/16

Uncredited Actors:Don Anderson remains on the scene as the ninth season begins. He first appears as a tuxedo wearing guest at one of the art gallery functions where Mr. Stange, after welcoming Perry and Della, saunters over to banter with him and a woman companion. Later, Anderson can be seen over Burger’s shoulder in the courtroom gallery. Submitted by FredK. 3 December 2010.

Sightings: Seated in the back row of the courtroom gallery is a recurring extra we call Quiet Old Man #1. Submitted by gracenote, 5/9/2011.+I believe Miss Carmody is in the gallery, shown as a bit blurry on the long shots when Perry is speaking, but I think it is her wearing a hat. ;-> Submitted by mesave31, 02/16/15.

This is one of the few episodes in which the murder victim is not shown. Submitted by Mason Jar, 8/17/2011.

This is the first of fifteen PM writing credits for Orville Hampton, who would later have five writing credits on "The New Perry Mason" television series...MikeM. 3/6/2017

Richard Anderson (1926-2017)Three Score Years and Ten is the Biblical formula for the length of a person's life; that, less then ten, was ultimately the duration of the PM cast, for with the passing of Barbara Hale earlier in the year - the sixtieth since the show began - and of Richard Anderson Thursday night, the regular cast is now gone (note: I exclude Karl Held from this category). Anderson would permanently join the show with this episode, and close out the series, as the LAPD presence (he had appeared in two earlier episodes as different characters, and would also appear in both The New Perry Mason, and with Raymond Burr in Ironsides). The introduction of Steve Drumm, Anderson's character, was something of a new direction for the show: Drumm's predecessors, Lts. Tragg and Anderson, had been an irreverent wit and a low key personality, repectively, but he was pretty much all business... sometimes civil. more often hostile, but never joking. Whatever levity that was introduced on the show would likely come from the other new character, restauranteur Terrance Clay (Dan Tobin); and with that, for better or worse, PM would move toward becoming a lot more like the other police shows of the period.
